3.1.1 Console Port
For local management, you can use a computer with terminal emulation software configured
to the following parameters:
• VT100 terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.1.2 Gigabit Ethernet Ports
The Switch has 10/100/1000 Mbps auto-negotiating, auto-crossover Gigabit Ethernet ports. In
10/100/1000 Mbps Gigabit Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and
the duplex mode can be half duplex (for 100 Mbps) or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed and duplex
mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or
crossover Ethernet cable.
3.1.2.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
• Duplex: Auto
Four Dual
Personality
Interfaces
Each interface has one 1000 Base-T copper RJ-45 port and one Small Form-Factor
Pluggable (SFP) fiber port, with one port active at a time.
• 4 100/1000 Mbps RJ-45 Gigabit Ports:
Connect these Gigabit Ethernet ports to high-bandwidth backbone network
Ethernet switches.
•4 Mini-GBIC Ports:
Use mini-GBIC transceivers in these slots for fiber-optic connections to backbone
Ethernet switches (see Section 3.1.3 on page 47 for instructions).
